Just thought I'd demonstrate an idea I've been experimenting with...
http://sdrv.ms/14ygEpU
The first part is a little tool that loads a 256 colour .GIF image file, and from that generates two other files:
* A 16x16 palette image, containing the original 256 colours.
* A copy of the original image with a modified palette, so that pixels are replaced with their palette index. So for example, if palette index 10 is pure red, all red pixels in the image are replaced with the color RGB:10,10,10.
The second part is a pixelshader that can load the palette image at runtime.
So the step by step process would be:
1. Create your 256 colour GIF image (if your object is animated, make sure you include all the animation frames in the same image).
2. Generate the special palette and image files.
3. Import the special image file into MMF2.
4. Edit the palette file to make all your different versions.
5. Apply the desired palette file as an HWA effect parameter.
It's still rather glitchy at present (having a lot of trouble with transparency), but seems like it has potential.

That's pretty cool. I've just been parting out my sprites, removing all the color information then using the tint shader on the different parts, but a palette swap would probably be a little less wasteful.

IIRC, you need your sprites to be made from lots of pieces anyway, because that's how your animation system is built - so what you're doing sounds like a sensible way to go.
This is really more for retro games. It could be applied to individual objects (eg. to change the colour of a character's clothing), or to whole layers (eg. to change a desert level into an ice level).

Actually, all my sprites are rendered, the animation system I use is based on two parts, one for the template based art, and another to control how the animation runs in MMF2. If I were brilliant enough, I could probably program up a system for the first part, which would probably allow me to input even more complex animations.
